Oil leaking on my GL1100

Postby Gnosistika » Tue May 31, 2016 8:06 am



Hi Guys,

Another post in a list about getting the old girl running again properly.

So the weekend past I took the bike out for a ride, a pleasant two hour cruise and she was going wonderfully. Then this morning however when I checked in on her to wash her on my off day I was met with a disturbing site - There was oil leaking [slow drip] from: the oil filter cap, from the oil drain plug, oil spray from the tachometer area, oil from the rear engine gasket. She now has less than a quarter of oil when I check the oil level. Also need to mention that there is no longer any oil dripping.

This is quite frankly freaking me out. When I rode her last i detected no hot oil smells and after i put her up there were no leaks. The only thing that changed is that the temperature has dropped to the low 2ºC (35 F) as we now entered winter here over the last number of days (not that is relevant at all). I have been so vigilant in checking everything - the carb balance was supposed to be the last bit of work to finally get her going... Was I blind or ignorant of any signs that I could have detected beforehand?

Ideas?

Well this may be an issue of old gaskets being dry/brittle and with the lower temperatures (constriction) of the gasket materials, and now you have leaks. If you just had one small leak, I would suggest trying some liquid 'stop leak' in a can solution, but in your case it may be simply time to replace the affected gaskets. (I'm assuming no excessive gas pressure build-up in the engine and regular dino motor oil is being used of the recommended weight.)

I would clean all the oil off, then run the bike and see if you can figure out where it is coming from. I doubt you've suddenly got multiple leaks all over, more likely you've got one leak that has sprayed oil all over everything else.

@WingAdmin

I did the little test but had to wait till this morning for evidence. The oil is coming from the oil filter area, I think that maybe the O-Ring failed, although it is new. The only other I discovered is oil spray from the tachometer area - where the cable enters the machine.

Thank you again sir. Really appreciate your assistance.

Could also be the O-ring didn't seat properly, or rolled or pinched.

Thank you guys for your help, much appreciated.

Strangest thing though. I had two oil-filter housings, the one that came with the bike and a second i picked up off from a guys selling his goldwing for spares - nice chrome piece it is too. I had put the chrome cover on and that when it started leaking. I replaced the o-ring first as @Wingadmin suggested but it kept leaking. Only after I put the original cover back did the leaking stop completely.

I had a look at the chrome to cover and to my eyes they seem identical...maybe it is from an Aspy or another model, though the seller insisted it was an '82. Strange things indeed.

Thank you again for the help gents!

Probably not flat/flush edge; aftermarket stuff not always true!! Or bad o ring..?? didn't you change/swap the o rings with the filters or kept them together with the filter housing???

Note, If i remember correctly all the oil filter housings 75 to 83 are the same..different bolt heads sizes i forget if they got bigger or smaller but that changed..


HAD LOTS OF GOLDWING 75-83
NOW INTO 1500'S..RIDING A 1998 SE

FAIR WINDS,
RB
